This blog is about a master thesis on visualization of recommender system processes, titled Visualization of Music Suggestions. The thesis a part of the program Master in Applied Computer Sciences at the Catholic University of Louvain (KUL). The thesis promotor is Prof. Dr. Ir. Erik Duval, and the thesis supervisors are Dr. Joris Klerkx and Prof. Dr. Katrien Verbert. Professor Duval and Dr. Klerkx are members of the HCI research group at the KUL.

The goal of this thesis is to design, implement and evaluate visualization and interaction techniques that allow the user insight in the recommendation process as well as actively steer the process. The elaboration of this thesis consists out of a literature study on the topic of visualization of music suggestions, and secondly a similar application that is designed and implemented.

In the design of the application findings of the literature study and comparative study of visual explanation systems are taken into account. From this initial design a hypothesis and expected result are derived. This hypothesis is tested through user tests. If possible, the application is improved. This process can be repeated, incrementally improving the application.
